**Research:**

Theoretical, experimental, and numerical studies in turbulence; subgrid-scale modeling for large eddy simulations; applications of fractals. Turbulent flows occur in a wide range of applications and have a large impact on drag, mixing, unsteady loading, etc. Progress in their efficient calculation is hindered by the existence of a wide range of excited temporal and spatial scales. An important problem is to model the small scales for large eddy simulations of turbulent flows. This modeling problem is addressed experimentally, analytically, and numerically for a variety of canonical flows, such as high Reynolds number wakes, turbulent jets, and grid turbulence, as well as for non-canonical flows such as rapidly strained turbulence or complex flows found in turbomachines. Scaling properties of turbulence are described and modeled using fractal geometry and multifractal statistical methods.

Current research projects include:

"Turbulence subgrid modeling in complex flows" (National Science Foundation);

"Effects of straining, spectral scrambling,
and rotation between resolved and subgrid scales of turbulence,"
with J. Katz (Office of Naval Research);

"Turbulence and Complex Flow Phenomena in Axial Turbomachines,"
